Would just removing the whole "The trip points..." sentence be ok? I see how it is more confusing than helpful.

I would have assumed the h/w supports some number of thresholds causing some action whether an interrupt or some sort of shutdown. Rob

That is true, but after the mentioned change only 3 are used at the time: one lower than current temperature, one higher than current temperature, and one for the critical temperature. So, from the perspective of somebody writing the devicetree source file this limit is probably irrelevant?
